Specification of Letters Patent.

Patented July 7, 1914.

Application filed March 8, 1913. Serial No. 752,948.

To all whom it may concern:

Be it known that I, RUDOLF SOHMITT, engineer, a citizen of the GermanEmpire, and resident of Frankfort-on-the-dain, Germany, with thepost-office address Rotlintstrasse 45, have invented new and usefulImprovements in Devices for Feeding the Tobacco in Cigar-BunchingMachines, of which the following is a specification.

Thi invention relates to improvements in the cigar bunching machines towhich the tobacco is supplied by placing the requisite quantity oftobacco in the hopper of the pressing device.

According to my invention the machine is provided with a fore-mold whichserves to roughly shape the tobacco before it is submitted to the actionof the press, saidmold being made in two portions one of which moves upand down with the jaws of the press while the other i carried by a leverwhich is swung to and fro over the hopper and actuated by a cam or thelike. In addition, I provide a check device constituted by a bell-cranklever, one limb of which looks the lever carrying the reciprocating halfof the fore-mold when its other limb is no longer encountered by a pinon the slide owing to an accumulation of tobacco in the press, saidcheck device being an improvement on devices which are at presentemployed in cigar bunching machines of the kind in which the tobacco isfed to the press device by means of a belt conveyer and which come intooperation and check the movement of the feed device when the tobaccoaccumulates, which device are extremely complicated and correspondinglyexpensive and unreliable. The device of my invention, on the other hand,is simple,

cheap and absolutely reliable.

The invention is illustrated in the accompanying drawing wherein- Figure1 is a side elevation, Fig. 2 a section through the press device, Fig. 2a view of the sifting plate from above, and Fig. 3 a plan of thefore-mold. Fig. 4 shows the device in a different position from that represented in Fig. 1. Figs. 5, 6 and 7 show the various cams for operatingthe device; and Fig. 8 is a cross section through the hopper, siftingplate and slide.

Above a table 1 rocks a lever 3, pivoted at 2 and carrying on its lowerend at 4 the onehalf ofthe fore-mold. The lever 3 is prov1d ed w1th aspring 5 which tends to draw 1t inwardly and is forced out by a bar 6which receives motion from the bell- .the fore-mold (Fig. 3) is seated.on the pressure member 16 carried by the lever 17, the latter beingpivoted at 18 and subject to the action of a spring 19. Motion istransmitted to the lever 17 through a connecting rod 20, from the lever22 pivoted at 21, the free end of this lever moving, by the aid of theroller 23, over the cam 24, which is separately shown in Fig. 5.

The pressure member 16 i provided, underneath, with a trough 25 throughwhich the slide 26 (Figs. 2 and 3) is adapted to pass. The reciprocatingmovement of the slide 26 is imparted through a bar 29 which is guided ina straight line at 27 and 28 and is operated by a push bar 31. The pushbar is actuated by the bell-crank lever 33 which is pivoted at 32, andthe free end of which runs, by the aid of a roller 34, over the triplecam 35 (Fig. 7). In this case also, a spring 36 keeps the roller pressedagainst the cam 35.

The pressure member 16 moves up and down in a hopper 37, the bottom ofwhich is formed by a sifting plate 38 (Fig. 2 pver which plate the slide26 travels to and Another regulating device is provided in the form of abell-crank lever pivoted at 39 and having one arm 40, situated withinthe sphere of action of the pin 41 arranged on the push bar 31. Theother arm 42 of this bell-crank lever serves as a locking arm for thelever 3 and prevents the same from moving when the arm 42 is in theposition shown by dotted lines in Fig. 1. v

'The. device works in the following manner. In the first place all theparts being in the positions shown in Fig. 1, the tobacco is laid byhand between the two parts 4 and 15 of the fore-mold. 'On rotating themain shaft of the machine, the press jaw 16, and with it the half 15 ofthe fore-mold, is

lifted as shown in Fig, 4. At the same time i the push bar 6, under theaction of the corresponding operating cam, ismoved rear-v ward, so thatthe spring 5 brings the lever "3, and with it the half 4 of thefore-mold,

into the positionvshown in Fig. 4, the tobaccothereupon falling out ofthe foremold into the hopper 37, on to. the plate 88. The press jaw 16then descends. under the action of the cam 4 and c'ompresses thetobacco, and at the same time all the dust falls through the holes inthe sifting plate and 4, so that the lever B is free to move.

If however, the tobaccohas accumulated in the press device or on thebelt conveyer 43 to such an extent as to prevent the slide 26 fromcompleting its stroke, the pin 41 fails tor'each the arm of thebell-crank lever, and consequently the other arm 42 of the said leverremains in the position in I dicated by dotted lines in Fig. 1, andpre-' vents the lever 3 from moving. In such case this lever cannotdischarge the tobacco lying in the fore-mold 4, 15, into the hopper, andthe operator must refrain from placing any more tobacco in the fore-molduntil the slide moves far enough forward to allow the pin 41 toencounter the bell-crank lever 40, thereby releasing the lever 3 andemptying 1 the fore-mold into the hopper.

Now what I claim and desire to secure by Letters Patent is" thefollowing;

1. In devices for feeding the tobacco i-n cigar bfunching machines thecombination of the. tobacco presser with a fore-mold made of twoportions, of which the one moves up and down with the pressure jaw,

while the other one rocks to and fro over the hopper of the presssubstantially as and for the purpose described.

. 2. In devices for feeding the tobacco in cigar bunching machines thecombination of the tobacco presser with a fore-:mold auto maticallydischarging thetobacco into the hopper, which fore-mold is made of twopor-.

tions, of which the one moves up and down with the pressure jaw, whilethe other one rocks-to and fro over the hopper of the presssubstantially as and for the purpose described.

3. In devices for feeding-the tobacco in cigar bundling-machines thecomblnation of the, tobacco presserg with a fore-mold automaticallydischarging the tobacco into the hopper, which'fore-mold is made of twoportions, of which the one moves up and down with the pressurejja w,while the other one rocks to and fro over the hopper of the press movedby a cam or the like substaniti ally as and for thepurpose described.

4.

5. In devicesforzfeedingthe tobacco in cigar bunching machines thecombinat on of the tobacco presser with a fore-mold and a checkingdevice COIlSlStlIlg of a bell-crank lever for preventing the movement ofthe fore-moldsubstantially asand for the purpose described,

'6. In devices cigar bunching machlnes the comblnation of the tobaccopresser with a fore-mold automatically discharging the tobacco into thehopper,'which fore-mold is made of two portions, of which the one movesup and down with the pressure jaw, while the'o-ther' one rocks to andfro over the hopper of the press moved by a cam or the like,:and achecking device consisting of a bell-crank lever for preventing themovement of the one portion of the fore-mold substantially .as and forthe purpose described.

In testimony, that I claim the foregoing as my invention, I have signedmy name I in presence of two witnesses, "this twenty for feeding thetobacco in fourth day of February 1918. A
